Payment & Refund Policy

Sales described here are made by Kagaku Nippon Technology Co., Ltd. (果格日本科技株式会社). The full statement of trading conditions required by the Japanese Act on Specified Commercial Transactions is published at 特定商取引法に基づく表記.

1. What we sell

• Credit pack: a one-off purchase of 200 credits, added immediately. It does not auto-renew.
• Creator Pass: 1,000 credits each month, with a commercial licence and priority generation. It renews automatically.

Prices are shown in the currency for your region and include consumption tax. Credits are an in-app balance: they cannot be withdrawn, exchanged for cash, or transferred to another account. Credits bought in a pack are valid for one year from the date of purchase; any unused balance expires after that.

2. How you pay

Payment is handled by Stripe and, in some regions, by local payment providers. We never see or store your card details. Credits normally arrive within seconds; if nothing has arrived after 30 minutes, contact us with your order number.

3. Renewal and cancellation

• Subscribing authorises a charge at the start of each billing period until you cancel.
• You can cancel at any time from Orders & credits, which opens Stripe’s billing portal. Cancel before the next charge date or that period is still billed.
• After cancelling you keep the credits and benefits of the current period until it ends. Nothing further is charged.
• Monthly credits do not roll over. Use them within the period they were granted.

4. Refunds

Credits are a digital good delivered immediately, so they count as delivered once granted. We handle refunds as follows.

• Full refund: within 7 days of purchase, provided none of that order’s credits have been used.
• Refund on request: where a technical fault on our side meant credits were never granted, where you were charged twice, or where the service was unavailable for an extended period.
• No refund: orders whose credits have been partly or wholly used; subscription fees for a period that has already begun and been credited; accounts restricted for breaching the Terms of Service.
• Failed generation is not a refund matter. When a generation fails the credits it consumed are returned to your account automatically — there is nothing to claim.

These rules do not affect rights you have under the Japanese Consumer Contract Act or mandatory consumer protection law where you live.

5. How to request one

1. Email infobg.b@lunf.ai with your registered address, the order number and the reason.
2. We review and reply within 3 working days.
3. Approved refunds go back to the original payment method. Your bank decides how long that takes, usually 5–10 working days.

6. Disputes and chargebacks

If a charge looks wrong, contact us first. Opening a chargeback with your bank suspends the account until the dispute is resolved, and we will supply the transaction records to the payment provider.

7. Price changes

Prices may change. A change never affects an order already placed. For subscribers a new price applies from the billing period after the announcement, and we will give at least 30 days’ notice by email, so you can cancel before it takes effect.

8. Contact

Payment and refund questions go to infobg.b@lunf.ai, or through the Contact page.
